g' UNTTED sTATEs PATENT oEEioE FREDERICK HENRY PERRY, OF BEVERLY,MASSACHUSETTS, ASSIGNOR TO UNITED SHOE MACHINERY COMPANY, OF PATERSON,NEW JERSEY, A CORPORATION OF NEW JERSEY.

Specification of Letters Patent.

Application filed February 12, 1908. Serial No, 415,567.

To all whom 25 may concern.'

Be it known that I, FREDERICK I-I. PERRY, a citizen of the UnitedStates, residing at Beverly, in the county of Essex and Commonwealth ofMassachusetts, have invented certain Improvements in ll?atterri-Gener-lThis invention relatesto mechanism forv generating patterns, and is ofespecial utilvity when employed in the production of patterns for solerounding machines for use in the manufacture of boots and shoes,although I contemplate the use of my invention in any field to whichitis adapted by the nature of my improvements.

My device may be used to notable advantage in conjunction with a modelor a sample shoe, constituting the primary pattern, to reproduce uponthe periphery of a pattern blank or disk the niceties of contour whichare formed by variations in the width of the sole edge, z'. e., thatportion of the sole which projects and is visible beyond the upper ofthe shoe. The pattern thus produced may then be employed ina ma-. chineof suitable'construction for trimming I or rounding soles previouslyattached to the uppers, preferably one of a type which I have inventedfor the special purpose, and

which is 5 disclosed in my co-pending applil cations for U. S. LettersPatent, Serial No.

559,332 iiled May-- 4,1910, and Serial No.. 679,765 renewed February 24,1912, atype] of machine in which mechanism controlled l by the patternacts to trim the soles of4 any desired number of shoes operated upon, to

form on their edges a counterpart of the model or of the peripheralcontour of the sole edge of the sample shoe.` In most shoes the edge ofthe sole is of varying width and,

the contour-of the soley is an important factor in its appearance, itbeing of course parmachine, which is used to round soles al-4readyattached, to secure the proper contour for the sole edge of a shoehaving a sole edge of varying width byy imitation of a sample sole edgeand this has been one of the mosty diiicult and responsible operationsinthe manufacture of shoes.

Variations from the sample have been usual; `often the discrepancy hasso marred the style as to diminish the value of the product;occasionally mated shoes have varied from each other so seriously thatone or. both has required alteration, with result-k ant expensive lossof work, and not infrequently one Vor both of the pair is discarded withcomplete or` partial loss of material.

To eliminate .the personal factor is an important object of myinvention, and as the varying projection of the sole edge furnishes thecharacteristic to be reproduced, I provide according to the preferredembodiment of my invention pattern-or model-copying mechanism, includinga guide or abutment preferably rotary, to be engaged and traversed bythe sole edge or other suitable model. and preferably actuatedpositively to feed the model at a speed having a constant ratio'to thespeed or rotation of the disk to be patterned, until the entire lengthof the model surface Yhas traversed the feeder; 'and concurrently withthis traverse of the sole edge, a follower member, also forming part ofthe copying mechanism, is maintained inv contact with the travelingsurface of the'shoe upper adjacent the region of the sole edgecontacting with the abutment or rotary feeder; the follower'projectingover the edgeyof the sole and beyond the edge of the abutment to anextent varying with the changing width of those por- Patented May28,1912.

tions f. of the sole edge traversed, and` correswings therewith as aunitary relatively rigid structure about a pivot, to maintain thefollower in operative contact with the primary pattern and to maintainthe cutter in corresponding varying operative contact with the blankdisk to be cut to pattern. The disk after having been thus patternedcorresponds detail for detail with the sole edge or other model orprimary pattern, and is ready for use in the sole rounding machine. Itmay be used also as a master pattern in the production of similar diskseither by causing it to traverse the rotary abutment while anotherpattern disk is engaged operatively by the rotary cutter, or byarranging the master pattern disk coaXially with respect to the blank ordisk to be cut to pattern, rotating them in unison, and arrangingcoaXially with the rotary cutter a follower disk or device which willengage the periphery of the master pattern disk and regulate the depthof cutting effected by the cutter, according to the varying radii of therotating master pattern disk.

Another important object of my invention is to provide means to mark thepattern at points easily visible to the operator of the sole-rounding orother machine in which the pattern is to be used, so that the operatorin setting the stops which control the operation of the roundingmechanism preparatory to use of the pattern can readily see by the markupon the toe-shaping portion of the cam, where to set the stop whichcontrols the operation of the rounder upon the toe of the shoe; andother salient features of the sole edge will be observed in marking thepattern, so that if the operator follows these indicia faithfully he canset the stops on his rounding machine with accuracy, insuring therounding of the sole edges to correspond closely with that of the sampleshoe.

Means to throw the rotary cutter out of operative position at will, andmeans to maintain it out of operative position, independently of theactuating mechanism, are also provided; and I have included also meansto hold the cut-ter at a point of operation where it will shapeautomatically the inactive limb of the pattern, which term I will usehereinafter for the sake of brevity to designate that portion of theperiphery of the pattern which is usually inoperative in thesole-rounding or other machine in which the pattern is used eventually.This limb will preferably be of uniform radius.

My invention contemplates also the simultaneous production of aplurality of patterns by the use of a cutter or other generator whichwill engage and shape at the same time a number of disks arrangedcoaxially. To facilitate this I have devised connectors applicable toadjacent disksand serving to couple them together for co-rotation witheach other and with their actuating shaft.

Other objects of my invention comprise means preferably formed inconnection with the pattern actuating shaft or other work support toenable the operator to locate each blank in proper position so that thegenerator will start work at a similar predetermined region of eachblank; also means for regulating the feeding mechanism of the model andthe blank independently of the generator, where the generator,model-feed and blank are driven from a common source of power.

The invention will be more fully explained in the following description,reference being had to the accompanying drawings, in which is shown oneform of apparatus by the aid of which the invention may be practised.

Fig. 10 is a view from the front of the machine withthe casing broken away; and Fig. ll is a view in rear elevation of themachine to show the arrangement of levers, etc.

The machine herein shown for practising my invention comprises agenerator 1 of any suitable construction, taking in the instanceillustrated the form of a rotary cutter mounted upon, and actuated by, avertical shaft 2 carried in bearings 3 near the end of a swinging arm 4mounted securely, as by shrinking or otherwise, upon a vertical shaft 5,the latter being removably and rotatably mounted in a hollow bearingbushing 6, (see Fig. 9) carried by the vcasing 7, which may rest on atable or other suitable support and be secured thereto by fasteningmeans passing through the lugs 8.

The hollow bushing 6 may serve as the bearing for the main actuatingpulley 12 of the machine, actuated by any suitable means, one convenientform of such actuating means being illustrated at 9 which designates abelt running around idle direction pulleys 10 and 11,. (from a suitablesource of power not shown) to the lower groove of the pulley 12 loose onthe vertical ybushing 6, the upper groove of this pulley serving toreceive a belt 13 running to a pulley 14 on and driving the verticalgenerator shaft 2 and its attached rotary cutter 1 whatever the angularposition of the swing arm 4. 15 is a take-up pulley for the belt 13,(see Fig.,2).

The disk or blank 16 to be cut to pattern or otherwise shaped, (see Fig.2) is mounted in the same horizontal plane with the generator 1, whichcuts into the periphery of the blank to a degree depending on thedistance between the aXes of the cutter and blank, this being determinedby the angular position of the swing arm 4 relatively to thelongitudinal axis of the machine. This angular positioning of thegenerator arm may be regulated by any convenient and suitable means,manual or mechanical, and in Figs. 1 and 2 I have shown a follower andregulating device 17 of a character especially useful in copying thesole 1S of a shoe 19 whose upper 2O is presented by the operator forrunning` engagement with the nose o-f the follower. A spring dog orplunger 21 mounted at 22 in the casing 6 presses against the heel 23of.the swing arm,

normally forcing the generator and fol-v lower leftward to engage thedisk 16 and shoe upper 20 respectively. In the instance illustrated, thefollower 17 4is mounted, (pivotally preferably, to permit smoothtraversal by the shoe) near the free end of an arm 24 connected with theswing arm 4, and which may be Yformed integrally or as aunitarystructure with the latter and swinging therewith over the sole edgeportion 25 as the operator `moves the same along past a guide orabutment 26.

The sole edge narrows toward the tip in the instance illust-rated, andas the operator passes the shoe along towardy the left, from theposition shown in Fig. 2, until the point 27 is reached, maintaining theedge 25 of the sole in engagement with the abutshould correspondcloselyin detail with the contourof the sole edge 18-27 and thence alongthe opposite side of the' sample shoe,

and in order to insure the movement of the sample at a speed bearing afixed ratio to that of the disk which is being cut to patf tern, whetherthe speed be higher or lower, I prefer to construct-the abutment 26 as arotary part and provide for its co-rotation with the vertical post 30carrying the disk 16, by suitable connections with the main actuatingpulley 12. In the instance illustrated I have shown for this purpose ahorizontally disposed counter shaft 31 mounted rotatively in bearings32, (see Fig. 1) on the base of the machine and driven by a spiral gear33 meshing with a worm 34 on ,the hub of the pulley 12, the countershaft 31 carrying a sleeve member 35 provided with a driving worm 36which meshes with a gear' 37 on the vertical shaft 38 (see Fig. 4), andthrough it and the clutch 71 drives the pattern blank disk 16.

The rotary abutment or feed wheel 26 (see Fig. 3) receives its actuationthrough 'a vertical shaft 39 mounted in a frame pillar 40 and carrying arelatively small gear 41 which meshes with a 'largerintermediate gear 42mounted on a stud or bolt 43, and actuated in turn by a gear 44 fast onthe vertical shaft 38. The gears 42 and are preferably considerablylarger than the gear 41, to cause faster rotation of the rotary abutmentor feeder 26 thanof the disk 16, and the abutment' preferably haspehipheral teeth or roughnessesto engage and feed positively thesole-edge pressed thereagainst, and may have a guide flange 45tofposition t-he sole properly with relation to the feed wheel; and alsoto position the upper 2O with relation to theA` follower 17, as seenbest in Fig. 3.

In order to permit stoppage of the rotation of the pattern blank disk atany de.

sired point regardless of the continued ro-. tation of the mainactuating pulley 12 and the generator 1, I 'prefer to interpose a clutchdevice between the counter shaft 31 and the feed devices, and as oneconvenient form of such a clutch device (see Fig. 7) I have formed theworm 36 upon a sleeve 35 mounted loosely on t-he counter shaft '31between collars 46, 47 fastened to the shaft by pins 48, this wormsleeve constituting one member of the clutch, and preferably beingprovided with a split brake block consisting of two halves 49, 50embracing the sleeve 35 and secured in adjusted position by a screw 51.rIhis brake serves to stop the worm sleeve promptly upon disengagementof the clutch, so that the pattern blank disk will not be fedimproperly. The other member of the clutch (See Fig. 7) consists of acap 52 having a head portion 53 provided with a pin 54 traversing a slot55 in the shaft 31 and serving to communicate the motion of the shaft 31to the cap, which in turn operates the worm sleeve through the medium ofa pin 56 and socket 57 connection. The cap 53 can be grasped manuallyand drawn outward axially toward the left to disengage the sockets fromthe pins, when the action of the brake 49, 50 will stop the rotation ofthe worm sleeve 35; but the cap cannot be withdrawn completely from theshaft without removal of the pin 54.

Preferably the disengagement of the clutch members will be effectedbefore withorawal of the sample shoe from engagement with the abutment26 and the follower 17, in order to avoid the undue cutting away of theperiphery of the pattern, which would result normally under the actionof the cutter 1 pressed thereagainst by the spring plunger 21.

The swing arm 4 may be moved outward againstthe action of the plunger 21to swing the cutter away from the disk by any suitable means, and as oneconvenient form of such means I have shown (see Fig. 6) a bell cranklever 5S mounted pivotally at 59 upon the base of the machine, one arm60 of the lever extending upward into position to engage a coperatingdepending arm 61 integral with the swing arm, while the other arm 62 ofthe bell crank extends outward beyond the frame of the machine and isprovided with a connecting rod 63 extending downward to a treadle orother suitable operating device, (see Fig. 1). After the swing arm hasbeen moved outwardly by this means, I prefer to utilize suitable meansto hold it positively at its outer position of disengagement. Onesuitable device for this purpose is illustrated at 64 which designates adog mounted pivotally upon a rod 65 carried in lugs 66 upon the top ofthe machine base. Normally this dog will be left in the upright positionshown in Fig. 1, where it does not interfere with free swinging of thearm 4 toward the pattern blank disk, but when the dog 64 is moved downinto a horizontal position by the operator, the dog will be engaged bythe portion 67 of the arm 4 and the arm will be held outward away fromthe disk. A similar dog 68 may be provided, of such a length that whenit th erefrom.

is lowered into horizontal position it will stop the arm 4 in such aposition that the cutter 1 will engage the periphery of the disk 16 onlyslightly and will cut automatically to a given radius the limb of thedisk, z'. e. that portion of the periphery which will be inactive in thesole rounding or other machine in which it is used eventually.

Among the important objects of my invention, one of the most notable isthe provision o-f means to enable ready application of the pattern blankdisks to the vertical actuating shaft 88, and their easy removal Themeans which I prefer to use for this purpose may be seen best byreference to Fig. 4, in which the reference numeral 30 designates a postmember having a threaded shank 69, entering a threaded axial recess 7 0in the upper end of the shaft 3S, the latter' having a driving clutchmember consisting of a collar or flange 71 secured to the shaft by a pin72, preferably at a shoulder 78 provided to lsupport the driving memberior the flange 71 may be integral with the shaft 88.

The collar 71 is shown as having a beveled periphery 74 to receive acooperating friction clutch member 75 and drive it frictionally toactuate the disks to be cut to pattern, and this driven member may beconnected operatively with the disks by any suitable means. As oneconvenient form of such means, I have shown a spline 76 arrangedvertically within notches, one in the periphery of the clutch member 75designated by the reference numeral 77 and another in the periphery ofthe hub device 78, this notch being designated by the reference numeral79, the spline being held by a peg or post 8O inserted in a socket inone of the members, preferably the hub, in such a position that thespline extends vertically across from the clutch to the hub and alsointo a slotI S1 in the disk 16, thus coupling the clutch, hub and disktogether. lVhen the shaft 38 is rotated and with it the flange 71, theclutch member 75 is rotated also by frictional engagement with theflange, and in its turn rotates the hub 7S through the medium of thespline 76, and at the same time rotates the pattern blank disk 16carried by the hub, the disk having an aXial aperture 82 to receive theboss S3 on the lower side of the hub. By making the post member 30 ofthe shaft suiiiciently long, room can be provided to receive a pluralityof disks as 16, 85, at the same time, as shown in Figs. 4 and 5, eachhaving preferably a hub as 7S, 86 and a spline 76, 87.

Suitable means sho-uld be provided to retain the pattern blank disks inadjusted position and as one convenient form of such means, I have shownthe post 30 as having a washer or washers S8 to overlie the adja- (seeFig. 1) which permits the washer to embrace the threaded end 69 or areduced portion 90 of the post, while the thumbscrew wings 91 aresecured pivotally by a pin '92 in a slot 98 in the upper end of theshank of the thumb-screw, so that they can be turned upwardly into theposition 4indicated in dotted lines in Fig. 4, so that after the washer88 has been withdrawn the hub 83 can be raised readily and removed overi. the head of the thumb-screw and an uncut pattern blank disksubstituted for engagement by the cutter. y

After one disk has been cut to pattern, in the inanner already describedin connection with the use of a sample shoe as the primary pattern, Icontemplate the super-position thereon of another pattern blankdisk, asshown at 85 in Fig. 4, and the sample shoe may then be omitted, the disk16 alshown in Fig. 4. The lower position shown in Fig. 4 is occupied byit when a single pattern is being shaped. Two pattern blank disks may becut to pattern at once by using Y asuiiiciently long cutter as indicatedby dot-ted lines in Fig. 4.

It. is important that the cutting operation should begin always at apredetermined point, and to regulate this automatically any suitablemeans may be provided. I have shown for this purpose a swing arm 95mounted pivotally above the top ofthe casing at y96 upon a bolt 4S,which serves also in the instance illustrated as the vertical bearingfor the intermediate gear V42. The arm has preferably a beveledtip atits free end which can be held manually against the pattern blank disksupport'75y until the latter brings a notch 97 oppositev the tip 98andthe tip enters the notch. When the machine is ready for operation thetip maybe withdrawn readily by'swinging the dog outward, orit will clearyitself from the Knotch when the machine is started.

Another important object lof my invention is to provide means tok markupon the disk suitable indexV points which. can be readily observed bythe operator who uses the disk upon a sole ro-unding or other suitablemachine, so that the operator' 'can 'readily determine how to set thestops in [that machine so as to controlproperly rovice 118.

Iscrew post having been raised into the posiltation of theV patterndisk, it being understood that in a sole rounding machine the roundingdevices operate upon the edge of the sole to an extent correspondingexactly with the radius ofthe pattern at any given point. For example,referring to Fig. 2, the dot designated by the reference numeral 99,serves as a mark to indicate to the operator of the rounding machinethat a certain stop is to be larranged for stoppage of the pattern disk,inasmuch as that portion of the periphery of the pattern disk adjacentthe dot serves tocontrol the rounding of the tip, the, pattern havingitself been cut away in correspondence with the relatively narrowportion of the sole edge of the sample shoe at the region designated bythe reference numeral 27, in Fig. 2. p

As a convenient form of pattern marking device, I have shown (see Figs.2 and 8) a point` 100 carried near the free end of the spring shank 101of a hammer device 102 pivoted, as at 103, in a suitable housing orsupport 104 secured in the instance illustrated upon the top of the arm4 by screws 105. The hammer has an upwardly projecting portion 106against which bears a latter, but in such close proximity that theresiliency of the shank 101 will permit the point to engage the faceunder the influence of the hammer, as will now be described.v Upon theheel 112v of thehammer, Ihave shown a pivoted latch 113 engagedby aspring 114 normally pressing the latchoutward into `engagement with theperiphery of a rock shaft orV trigger 115 mounted ink a horizontalbearing in which it can be rotated'by a crank 116 (see Figs. 1A and 2)having a connecting rod 117 running down' to a treadle or other suitableoperating de- The rock shaft 115 has a notch 119 the wall of whichcatches the latch when the operator rotates the rock shaft by depressing the treadle, and upon further rotation of the rock shaft, thelatch is crowdedy out of the notch, releases the heel ofthe hammer andthe latter is forced downward by theY action of the spring 109, whichresults in a sharp, staccato blow of the point 100, causing a slight butperceptible indentation of the disk 16, as at the point designated bythe reference numeral 99 in Fig. 2. The rock shaft trigger 115 isreturned to normal posit-ion by a spring k120 acting upon release oftheconnecting rod 117. The general operation kof the machine is' asfollows :--,The wings y91 of the thumb Q tion illustrated in dottedlines in Fig. 4, the disk orpattern blank 16 with its hub 78 is placedover the upraised wings and dropped down into position over the clutchmember 75, with the spline or connector 76 extending from the notch 79of the hub into the notch 77 of the clutch member. The washer 88 is thenapplied horizontally with its notch 89 upon `the threaded portion 69 ofthe thumb screw post, the wings of the latter are turned downward andthe thumb screw tightened to hold the hub and' disk snugly in place uponthe clutch, which is cro-wded against the flange 74. If the cutter 1 isnot already rotating, the belt 9 may now be set in motion, and after theportion 18 of the shoe sole has been placed in contact with the abutment26 as illustrated in Figs. 1 and 2, the dog 64 is raised to permit theplunger 21 to swing the arm 4 around to bring the generator 1 intooperative cutting engagement with the periphery of the disk 16, thisbeing the position shown in Fig. 2, where the cutter has entered deeplyinto the disk and shaped the disk at that point in correspondence withthe relatively wide edge of the sole at the portion 18. r[his deep cutis permitted by the relatively' large displacement of the follower 17which has swung over into engagement with the upper at 20. The operatorthen presses in the clutch cap 53, the tip of the arm 95 is cleared fromthe notch 97 and the rotation of the counter shaft 31 is transmittedthrough the worm 36 to the gear 37, shaft 38 and thereby to the gears44, 42 and 41, and the shaft 39.

The abutment 26 is thus rotated to feed the sole edge 18-25-27 alongfrom right to left, the narrowing width permitting the upper to crowdback the follower 17, and at the same time the pattern blank disk 16 isrotated by 'the shaft 38 in the direction of the arrow, at a much lowerspeed, in the instance illustrated, but at a proportionately constantratio, so that the narrowing peripheral cut indicated by the broad dotsin Fig. 2 corresponds exactly in contour with the varying width of thesole edge. The operator should maint-ain the sole edge in true tangencywith the rotary abutment at a point lying in a line passing from theaxis of the rotary abutment through the midpoint 121 of the follower 17,and to assist the operator in accomplishing this I have shown a mark onthe follower at the midpoint 121 and a corresponding mark 122 on theadjacent arm 24, these marks, when alined, indicating that the sole isproperly positioned. After the portion 18-25-27 has traversed thefollower, the opposite side of the sole edge is caused to traverse inlike fashion, from the point 27 to the point 29 &c. causing the patternto be shaped, and then the dog 68 is dropped, the arm 4 allowed to restthereagainst, and the limb of the pat-tern is shaped automatically to acircle of predetermined radius. This completes the operation and theoperator will then depress the rod 63, throwing out the arm 4 and cutter1; will drop the dog 64 to hold the cutter away from the pattern; andwill replace the pattern by a new blank disk, first loosening slightlythe thumb screw, raising its wings 91, sliding out the washer 88 andwithdrawing the disk 16. As already indicated, the pattern 16 mayalternatively be left in place to serve as a master pattern, in whichevent a fresh pattern blank disk 85 (see Fig. 4) provided with a hub 86and spline 87 will be imposed upon the hub 78, and the upper washer 88will be placed in the upper groove 90 of the stud 30, presenting theappearance shown in Fig. 1. The retaining nut 123 and the cutter 1 willbe removed from the generator actuating shaft 2, a follower disk or roll94 will be applied to the shaft 2 and the cutter and retaining nut willbe replaced, after which the swing arm 4 may be released and the clutch53 coupled. rl`he follower roll or disk 94 will be forced, by the actionof the plunger 21, into engagement with the periphery of the masterpattern 16 at all points, accompanied by similar cutting engagement ofthe generator 1 with the pattern blank disk 85, which will thus beshaped as an exact replica of the master pattern 16, and furtherreplicas may be produced automatically without further attention to themachine than is involved in removing each replica as it is finished andsubstituting a fresh pattern blank disk. l

Vhile, in the use of a machine embodying this invention for producing apattern or a cam to be used in the manufacture of shoes, it may be moreconvenient to employ a sample shoe as a model in the manner hereinbeforedescribed, it should, nevertheless, be understood that the invention isnot limited to the use of a shoe as a model; although it is essentialthat such model as is employed shall have a shape corresponding incertain desired characteristics with the article in the manufacture ofwhich the pattern is ultimately to be used.
